Conversion Formula
The conversion from psi to mpa uses the formula: mpa = psi × 0.00689476. This works because 1 psi equals 0.00689476 mpa, based on the conversion factor derived from the relationship between pounds per square inch and megapascals. For example, converting 145 psi:
- 145 × 0.00689476 = 1.0005372
- So, 145 psi approximately equals 1.0005 mpa.
Conversion Example
- Convert 100 psi to mpa:
- Step 1: Use the formula: 100 × 0.00689476
- Step 2: Calculate: 0.689476
- Result: 100 psi equals approximately 0.6895 mpa.
- Convert 200 psi to mpa:
- Step 1: 200 × 0.00689476
- Step 2: 1.378952
- Result: 200 psi equals approximately 1.3790 mpa.
- Convert 50 psi to mpa:
- Step 1: 50 × 0.00689476
- Step 2: 0.344738
- Result: 50 psi equals approximately 0.3447 mpa.

Conversion Definitions
psi
Psi, or pounds per square inch, is a pressure unit measuring force applied over an area of one square inch. It is used mainly in the United States for tire pressures, hydraulic systems, and other pressure-related measurements, with 1 psi equaling about 6894.76 pascals.
mpa
MegaPascal (mpa) is a metric pressure unit representing one million pascals. It is used in engineering, physics, and material science to measure stress, pressure, and force per unit area, providing a standard for high-pressure systems and scientific calculations.
Conversion FAQs
Why is 145 psi approximately equal to 1.0 mpa?
This is because 1 psi converts to 0.00689476 mpa, so multiplying 145 psi by this factor yields about 1.0005 mpa. Small differences occur due to rounding but generally, 145 psi is considered roughly 1.0 mpa in practical applications.
How accurate is the conversion from psi to mpa?
The conversion uses a fixed factor of 0.00689476, which is highly precise for most engineering calculations. Minor discrepancies may happen in very sensitive scientific contexts, but for everyday uses, this value is sufficiently accurate.
Can I convert psi to mpa manually using the formula?
Yes, by multiplying the psi value by 0.00689476, you can convert any psi measurement to mpa manually. For example, to convert 145 psi, multiply 145 by 0.00689476 to get approximately 1.0005 mpa.
